适用范围：This standard covers certain electrical, dimensional, and mechanical characteristics and takes intoconsideration certain safety features of three-phase, 60 Hz, liquid-filled, self-cooled, pad-mounted,compartmental-type distribution transformers. These transformers are rated 5 MVA and smaller, with thehigh-voltage limit of 34.5 kV system nominal voltage and below, and with the low-voltage limit of 15 kVsystem nominal voltage and below. These transformers are generally used for step-down purposes from anunderground primary cable supply. This standard covers the connector, bushing, and terminal arrangementsfor radial- or loop-feed systems. Either certain minimum dimensions or certain specific dimensions shall bespecified. This standard does not cover the electrical and mechanical requirements of any accessory devicesthat may be supplied with the transformer.
